Altcoin Season Index at 57: Bitcoin Still Rules at 57% Dominance

Bitcoin dominance still frames the market

Bitcoin remains the market's main liquidity magnet.

BTC dominance sits at 57%, while Coin Glass's Altcoin Season Index is at 58 and CoinMarketCap's version is at 53. That is a meaningful shift in relative strength, but not a full regime change. Altcoins are getting stronger, yet Bitcoin still looks like the dominant trade.

What the two indexes are really saying

The two readings sit close enough to suggest the market is nearing a turning point, but not far enough to call it a clean break. Coin Glass at 58 is closer to a signal, while CoinMarketCap at 53 remains more cautious, reflecting each tracker's slightly different weighting and lookback methodology.

Both still use the same benchmark line: 75% of the Top 50 outperforming Bitcoin over 90 days defines altcoin season.

Why the setup still looks like a slow rotation

The nuance here is important. Altcoin momentum is real, but it does not yet look broad enough to displace Bitcoin altogether. The market may be in a slow rotation phase, where selective altcoins strengthen while Bitcoin still captures most of the market's core liquidity.

Until dominance softens enough to push the index toward that 75% threshold, Bitcoin's continued leadership remains the cleaner read.
